Distributive Property The Distributive Property is an algebra property which is used to multiply a single term and two or more terms inside a set of parentheses.

## Diameter – D – Breathmath’s Math Glossary

Diameter: A straight line passing from side to side through the centre of a body or figure, especially a circle or sphere. Diameter of the Circle: Any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. Diameter is the longest chord of the circle. Diameter is the twice of… Continue reading Diameter – D – Breathmath’s Math Glossary
